This isn't really specific enough to be a very strong argument. If by "you" you mean an entire country, then as
@innonimatu said the "natural" state of affairs would be for the citizens of the country to consume what they produce. In general the population of a country cannot consume what it produces because the extraction of surplus value leaves them unable to do so.
What is really happening is not trade based on comparative advantage. China does not produce the things that it exports so much more efficiently than other countries that it's actually efficient in terms of real resources to e.g. ship components to China for assembly then ship the finished product back overseas than to just assemble the components in their country of origin. The real reason for the huge volume of international trade and investment is that the business elite can profit through arbitrage, ie, due to the enormous differences in prices between Bangladesh and the US or between China and Germany.
Taking advantage of arbitrage benefits the business elite enormously, there's no question of that. But arguments for why it benefits everyone else are lacking.
That is the essence of the global "race to the bottom" and it's why solving the world's economic problems is going to require either the return of capital controls and other protectionist barriers, or an actionable international system to maintain things like labor standards, pollution regulations, etc and ensure that the rich cannot simply go wherever it's easiest to externalize costs.
